@discussion An instance of JSVirtualMachine represents a single JavaScript "object space"

virtual machine, with concurrent JavaScript execution supported by allocating

separate instances of JSVirtualMachine.

@abstract Notify the JSVirtualMachine of an external object relationship.

@discussion Allows clients of JSVirtualMachine to make the JavaScript runtime aware of

arbitrary external Objective-C object graphs. The runtime can then use

this information to retain any JavaScript values that are referenced
|
|
from somewhere in said object graph.
|
|
|
|
For correct behavior clients must make their external object graphs
|
|
reachable from within the JavaScript runtime. If an Objective-C object is
|
|
reachable from within the JavaScript runtime, all managed references
|
|
transitively reachable from it as recorded using
|
|
-addManagedReference:withOwner: will be scanned by the garbage collector.
